Task<\/strong><\/h1>\n

One construction company wants to minimize paint expenses. For this reason has to be made a program which can calculate an amount of a paint for the each order. Usually the owner know the longness L <\/strong>, wideness\u00a0 W <\/strong>, and highness\u00a0 H <\/strong> of the each room. Also one can of pain is good enough to paint\u00a016 m2<\/sup>, and the size of windows and doors are not important in this calculation<\/p>\n

\u00a0Input:\u00a0<\/strong><\/h1>\n

In the first line should be orders` amount. In the each next line —\u00a0 L, W, H\u00a0<\/strong> and the wideness, longness, and highness are not more than 1000 <\/strong>.<\/p>\n

\u00a0Output:\u00a0<\/strong><\/h1>\n

For the each order will be shown one one number, what is required amount of the paint cans \u00a0<\/p>\n
